Britney Spears is a single lady once more.

The pop princess told fans on Twitter that she is back on the market after splitting from boyfriend David Lucado.

"Ahhhh the single life!" she tweeted.

A representative for the singer - who is in Las Vegas for her Piece Of Me residency - confirmed she and David had gone their separate ways.

It comes amid claims that a video has emerged allegedly showing David looking cosy with another woman.

Britney, 32, had been dating David since March 2013, just a couple of months after she broke up with fiance Jason Trawick.

A source told E! News that the singer is "heartbroken" about the split, but went on: "But she will get through it. She's a strong girl and he was never right for her."
